DISEASE IN CATTLE RESEMBLING RABIES.

excited by the sight of a dog, or any other animal, although that 
increased it. Foam stood on their lips, and the gluey phlegm with 
which the mouth was filled, trickled ropily from the corners of the 
mouth. The hinder parts were weak : this was evidenced by 
their tottering gait, and increased so rapidly that, on the third day, 
the patient was mostly stretched on the ground, and could not be 
raised without great difficulty. The muscles of the thighs, the 
shoulders, and the face, were contracted, as by spasms, at intervals. 
If tied up, the animals were restless, gazed wildly about, and bel- 
lowed frequently : if free, they rushed straight onwards over every 
thing, until some obstacle impeded their path, and they fell head 
over heels, after which they lay still, apparently exhausted. 
They never seemed to betray actual frenzy. It was always pos- 
sible to approach them, seize them by the mouth, give medicine, 
and, if proper caution were employed, pass a halter over their 
heads and fasten them up. The most striking symptom was the 
rapidity with which the animals attacked by this disease fell 
away : not but what this symptom was easily explained ; for, from 
the moment of attack, all appetite seemed lost, rumination ceased, 
and the animal did not appear to feel any thirst. The power to 
swallow, however, remained unimpaired : any fluids which were 
poured into the mouth were sucked down, as bran, water, &c. ; 
and the only peculiarities observable were a choaking, and a 
twitching of the muscles of the face. In all the patients there was 
a tendency to constipation, and the dung was hard and brittle. 
The following symptoms were the results of a manual examina- 
tion : — The pulsations of the heart were full and tumultuous — the 
pulse full, and somewhat accelerated — the breathing was per- 
fectly natural — the febrile symptoms were not marked, and I 
did not perceive any exacerbations excepting in the morning, 
when the pulse was at 60 ; one horn was hot and the other cold, 
and a shivering was perceptible throughout all the muscles of the 
skin, and especially on the thigh. At other times in the day the 
pulse and heart were only slightly accelerated, and the tempera- 
ture of the whole body nearly equable, which plainly demonstrated 
the danger that was likely to arise from the deep hold the dis- 
ease had taken on the sensorial parts. 
The mucous membranes were crimson, the mouth hot, and the 
tongue dry and prickly. This last accompaniment of inflammation 
I have vainly endeavoured to find in any other animal. 
On the third day, all the animals suffering from this disease 
were reduced to a dreadful state of weakness. Until that period 
many of them were able to keep upon their legs, but beyond it, 
none : they lay either in the usual posture but with the mouth 
rested on the ground, or else stretched out, and so motionless that
